I’ve built an Email Outreach & Sentiment Detection Automation in n8n that completely streamlines the process of sending outreach emails, tracking replies, and analyzing sentiment with AI.
🔹 How it works
- Outreach Automation
The workflow kicks off on a daily schedule and selects 5–10 leads from a Google Sheet.
It loops through the selected contacts and sends out personalized outreach emails via Gmail.
Each sent email is logged back into Google Sheets with a status update (Sent) for full tracking.
- Reply Monitoring
A second workflow runs every 15 minutes to check for new unread replies.
It extracts the required fields (sender, subject, body, etc.) and checks if the email is indeed a reply to the outreach.
The content is cleaned up by removing quoted text, extra strings, and special characters so only the fresh reply remains.
- Sentiment Detection with AI
The cleaned reply is passed to an AI Agent powered by Google Gemini with Simple Memory and a Structured Output Parser.
The AI evaluates the reply and categorizes it (e.g., Positive, Neutral, Negative).
The result, along with the reply text, is logged back into Google Sheets with status = Replied.
🔑 Why this is powerful
✅ Outreach volume is controlled (5–10/day for natural delivery)
✅ Automated logging of sent & replied emails in Google Sheets
✅ AI-powered sentiment detection ensures quick triage of responses
✅ Scalable & hands-free – from sending, monitoring, cleaning, to analyzing replies
This automation essentially acts as a virtual SDR assistant — sending outreach, logging every action, and telling you instantly whether replies are positive or not.

Nice work—n8n is a great fit for stitching outreach + reply handling together.
A couple things that usually make sentiment automation more reliable in the wild:
If you ever want to pair this with lead sourcing/enrichment, our AI Lead generation solution can feed qualified contacts into n8n so the workflow starts with better targets.
